Example: Change States with Parameter Effectivity 

Create Change Master Records

You create two change master records with the SERNR (serial number) effectivity type, which is defined as standard. You define the following effectivity in the change master records:

Change Master Record	Material Number	Serial Number Interval
SER01	M1	1001 – 2000
SER02	M1	2001 – 3000

Create BOMs

On January 01, 2005 you create a bill of material with two items, with reference to the change master record SER01.

The standard system gives a BOM header date validity, which is valid from the date of creation. The items are assigned the effectivity from change master record SER01.

In Bills of Material Customizing you set the type of validity with which a BOM header is created, when you create a BOM with reference to a change master record with parameter effectivity:

·         The header is given the validity that is defined in the change master record

·         The header is always valid from the date of creation (standard)

You set this in BOM Customizing by choosing Control data for Bills of Material → Define Modification Parameters.

BOM Created using SER01

BOM Changing

You change the BOM with reference to change master record SER02:

·        You change the component quantity in item 20

·        You add another item

This is how the change statuses look:

Change Statuses after Changing using SER01

Item P20 now has two change statuses, which are valid according to various criteria.
